Zoo Escape

A breakout is planned by the farm animals from the petty zoo! Enough is enough! They can no longer deal with kids touching them, poking them, prodding them, screaming at them. They must get out or die trying!
It's your task to solve the puzzles on each level to allow the animals to roll to freedom! Use various objects in each level to grant freedom to each animal.
Pumpkins, onions, bales of hay, carts, wheels, boxes, barrels etc can be used to help you free those animals!
